General Information

The Chicago Manual of Style is used frequently in the humanities and social sciences. This guide covers the citation and reference portions of the Chicago Author-Date style but does not cover the writing style portions. 

The Chicago style is closely related to the style of Turabian's Manual for Writers of Research Papers, Theses, and Dissertations. Differences are noted in this guide so that it can be used for the Turabian style as well.

Note that citations in both Chicago styles should be double spaced, but to save space (and scrolling), they are single spaced on this guide.

Tutorials and Citation Engines

There are several online sites that will format your citation for you from the information you enter. Be sure to check the citation to make sure that it is correct according to the latest edition of The Chicago Manual of Style.

Books relevant to Chicago style


According to the Merriam-Webster's Collegiate Dictionary, to plagiarize is "to steal and pass off (the ideas or words of another) as one's own." When you use an idea, whether you completely rewrite the idea, paraphrase another, or quote the original, you must give credit to the originator of the idea using citations. Plagiarism at SDSU is governed by the SDSU Student Code, Chapter 1:10:25.
